Presentation Tip: Change the Font Size of the Windows Command Prompt

Standard

I have researched about Presentation Tips over past few weeks, one Tip that I read again and again is that “Make Fonts larger for readability”. To that end, I just changed the font size of the command line prompt so that when I am presenting, the audience is able to see what I am typing. So If you’ve have to present to audience something via command prompt, this should be of helps:

1. Open command prompt > Right click near the Title bar > select properties

command prompt change font size

2. switch to font tab > select the font and the size. you can also change the color, layout among other things here.

command prompt change font size font color layout

3. see how it looks:

Conclusion:

In this post, we saw how to change the Font size of the windows command prompt.

Addressing few Q’s a reader had about Google’s BigData offering BigQuery:

Standard

After reading First Impression: Google’s BigData offering called BigQuery , a reader (Shadab Shah) had few questions about it and in this blog-post, I am going to address those questions:

Q1. Any browser based Tool’s to Query data in BigQuery?

A1: They have a Browser Based Tool which they call “BigQuery Browser Tool” using which you can Query Data.

Apart from browser based, there are other tools too:

1) a command line tool called “BQ command-line tool. You can find more information here: https://developers.google.com/bigquery/

2) API. one can “include” big data analytic capabilities into a web app via RESTFul API. (Point #2 content credit: Michael Manoochehri’s comment)

Q2) Where is the Data Stored? 

If i just say “Google Cloud” that would not be a complete answer. There’s a complementary service called “Google CLOUD SQL” and so I do not want you to confuse data stored for BigQuery with “Google cloud SQL”.Theres’ a difference between BigQuery and Google cloud SQL, you can read that here: https://developers.google.com/bigquery/docs/overview

Having said that, it’s stored on Google’s cloud and if you wish to use BigQuery – you’ll have to upload your data-set in a CSV format and if you do so, it’s stored in Google cloud and is ready to be analyzed via BigQuery.

Q3) Where do I find lots of data to play with BigQuery?

Google has few sample data-sets that you can play with:

That’s about it for this post. Thanks Shadab Shah for the questions, I hope this post is useful.
